DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved stationary skimming device for a swimming pool embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the stationary skimming device for a swimming pool 10 is comprised of a plurality of components. Such components in their broadest context include tubular frame pipes 12, 13, 14, a tubular side pipe 16, tubular connectors 18, 20, 22, 23, two screens 24 and two adjustable hooks 26. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

More specifically, seven tubular frame pipes 12, 14 and one tubular side pipe 16 are each fabricated of plastic and formed in a hollow generally cylindrical configuration with two open ends. The open end of each pipe includes coupling means 34 affixed therearound. The pipe ends are adapted to fit securely within tubular couplers in the operative orientation. The releasably coupled components of the apparatus permit easy assembly and disassembly by the user. Note FIG. 8. Additionally, each pipe includes adjustable coupling devices 36 affixed along its length. Each pipe also includes a plurality of radially positioned apertures 52 extending therethrough. The apertures allow water to fill the interior of the pipes to permit the receipt of water when submerged in a swimming pool. The submerged pipes help stabilize the apparatus. The coupling devices are adapted to secure the edges of the screens therein. The coupling devices are configured to permit tightening of the screens. Note FIG. 7.

The apparatus includes three vertically positioned pipes 12. Each pipe has an upper end and a lower end. One of the pipes is positioned inboardly with respect to the edge of a pool. One pipe is positioned outboardly with respect to the edge of a pool. The outboard pipe is positioned near the center of the pool. A central vertical pipe is positioned between the inboard and outboard vertical pipes. The apparatus includes two upper horizontal pipes 13. Each upper horizontal pipe 13 is positioned between the upper ends of the vertically positioned pipes. The ends of the inboard upper horizontal pipe are coupled to the inboard and central vertical pipes with three-way connectors. The outboard end of the outboard upper horizontal pipe is coupled to the outboard vertical pipe with an elbow connector. Note FIGS. 1 and 2.

The apparatus includes two lower horizontal pipes 14. Each lower horizontal pipe is positioned between the lower ends of the vertically positioned pipes. The horizontal pipes include a generally L-shaped shelf 50 which is formed contiguously with the adjustable coupling devices. Each shelf extends approximately radially from the coupling devices. Each shelf prevents captured debris from falling back into the pool when the user removes the apparatus for cleaning. Each of the lower horizontal pipes is coupled to the central vertical pipe with a three-way connector. The opposite end of each lower horizontal pipe is coupled to the adjacent vertical pipe with an elbow connector. Note FIGS. 1 and 2.

A single tubular side pipe has an inboard end 30 and an outboard end 32. The inboard end is positioned even with, and a short distance from the inboard end of the inner upper horizontal pipe. The outboard end of the tubular side pipe is positioned adjacent to the upper end of the central vertical pipe. The side pipe is coupled to the apparatus by way of a four-way connector. The tubular side pipe provides the apparatus with additional strength and stability. The side pipe is positioned upstream with respect to the flow of water to prevent bending of the device. Note FIG. 3.

Eight tubular connectors 18, 20, 22, 23 are fabricated of plastic and formed in a hollow generally cylindrical configuration with two or more open ends. Three elbow connectors 18 are formed in a curved L-shaped configuration with coupling means 34 affixed within their open ends. Two elbow connectors are positioned at the upper and lower ends of the outboard vertical tube. These tubes couple the upper and lower outboard horizontal tubes thereto. A third elbow connector is positioned at the lower end of the inboard vertical tube. Note FIGS. 1 and 2.

Two three-way connectors 20 are formed in a hollow generally cylindrical configuration with two linearly positioned open ends and a third open end which is positioned therebetween. A first three-way connector is positioned on the lower end of the central vertical connector. The inboard and outboard lower horizontal tubes are coupled therebetween. A second three-way connector is positioned on the upper end of the inboard vertical pipe. The inboard upper horizontal pipe is coupled therein. A four-way connector 22 is formed in a hollow generally cylindrical configuration with four open ends. The four-way connector couples together the two upper horizontal pipes, the upper end of the central vertical pipe, and the tubular side pipe. Note FIG. 3. The connectors permit easy assembly and disassembly of the apparatus. Note FIGS. 1, 2 and 3.

Two screens 24 are formed in a generally rectangular configuration. Each screen is comprised of a plurality of vertical and horizontally positioned synthetic fibers. The synthetic fibers form a grid configuration. A plurality of generally rectangular shaped holes is formed between the fibers. The edges of each screen are positioned within the coupling means 36 along the length of each horizontal and vertical pipe. Each screen extends between the horizontal and vertical pipes with a middle vertical pipe separating the screens therebetween. The coupling devices are adapted to permit the user to tighten the screens when deemed necessary. Note FIGS. 1 and 2.

The screens are adapted to catch debris floating on or under the surface of swimming pools as water circulates through. Bugs, leaves, and other debris get caught in the screen both above and below the surface of the water. To clean the apparatus the user simply removes the device from the pool. The screens may then be easily cleaned with a standard garden hose. The simplicity and efficiency of the apparatus permits users to cleanse their pools of most floating debris with a minimal effort. The apparatus is also effects cleaning in a very short period of time. Note FIG. 1.

Two adjustable hooks 26 each have an inboard region, an outboard region, and a central region therebetween. The inboard region 40 has a generally cylindrical shaped sleeve extending therefrom. The sleeve has an aperture which extends vertically through two diametrically opposing sides of the sleeve. A hollow adjustment tube 42 is formed in a generally cylindrical configuration and is positioned within the sleeve. Each adjustment tube has a plurality of vertically positioned apertures extending therethrough. A lock pin is formed in a solid generally L-shaped configuration. The lock pin 44 is adapted to be positioned through the sleeve and adjustment tube with the desired apertures positioned in vertical alignment. The adjustment tube can be moved to a variety of different lengths to accommodate the varying ledge widths of many different kinds of pools. Note FIG. 6.

The outboard end 46 of the adjustable hook has a generally L-shaped configuration. One end is adapted to be positioned in the central region 48, and one end is adapted to be positioned under the ledge of a swimming pool in the operative orientation. The central region is formed as a hollow generally cylindrical shaped member and contoured in an L-shaped configuration. The central region securely couples the inboard and outboard regions together. One adjustment hook is coupled with the three way connector at the inboard end of the vertical pipe. The second adjustment hook is coupled to the free end of the tubular side pipe with a linear two way connector. The tubular side pipe and cooperatively coupled second hook are adapted to help stabilize the apparatus as water flows through the screen. Note FIGS. 1 and 3.

The adjustment hook is adapted to permit a user to affix the apparatus to the edges of differently sized swimming pool edges in the operative orientation. To adjust the length of the adjustment hook, the user simply slides the adjustment tube further within the sleeve and aligns the desired apertures with those in the sleeve. The lock pin is then vertically positioned through the aligned apertures. The hooks securely affix the frame pipes and side pipe to the edge of a pool in the operative orientation. Note FIGS. 4, 5 and 6.

Relaxing in the comfort of a private pool is one of the most enjoyable of recreational activities. Inviting friends for pool parties and barbecues, or simply winding down after a hard day at work can make ownership and maintenance of a pool well worthwhile. In addition to the tasks of testing the water quality, cleaning the filter, and making a pool clean and safe, there is also the need to physically remove floating debris from the water. Conventional pool filters are effective only for the volume of water which is drawn into their inlets. Matter that remains must be extracted using a skimmer net, vacuum, or other suitable tool. But the task of skimming is very time consuming when done by hand, and must be performed at regular intervals. That is why the stationary skimming device for a swimming pool was conceived. The apparatus provides an autonomous method of skimming which can be operated unattended. It requires no electrical power and has no moving parts.

The stationary skimming device for a swimming pool is constructed from a rigid frame surrounding a synthetic screen material. The frame is made from weather resistant plastic and is assembled in a rectangular shape. There is a central vertical pipe at the center, and a side pipe attached at an angle to the upper horizontal pipes. There are also two adjustable hooks at each end of the frame where it is attached to the pool. The screen is installed between the frame segments and serves to remove the floating debris from the pool water.

To use the stationary skimming device for a swimming pool, the user simply hangs it over the side of a pool so that it extends straight outward toward the center. Most of the screen becomes submerged below the surface of the water to trap the debris. As the water slowly circulates around the pool, the debris is trapped by the screen. The apparatus can then be removed and hosed clean. Nothing could be easier.

The apparatus operates without power because the force of the treated water which exits from the filter exhaust is sufficient to provide the circular movement of the water. When floating bugs and debris swirl to within reach of the screen, they are collected from the surface. Depending on the severity of the contamination, the apparatus should be capable of cleaning the entire pool surface in just minutes. The stationary skimming device for a swimming pool is easy to install, maintenance free, and is almost certain to be appreciated by pool lovers nationwide.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
